PTHH: \(Zn+H_2SO_4\rightarrow ZnSO_4+H_2\uparrow\)
Ta có: \(n_{H_2SO_4}=0,3\cdot1=0,3\left(mol\right)=n_{Zn}=n_{ZnSO_4}=n_{H_2}\)
\(\Rightarrow\left\{{}\begin{matrix}m_{Zn}=0,3\cdot65=19,5\left(g\right)\\V_{H_2}=0,3\cdot22,4=6,72\left(l\right)\\C_{M_{ZnSO_4}}=\dfrac{0,3}{0,3}=1\left(M\right)\end{matrix}\right.\)
